Gowanda’s MLRF1812-331J is a high-quality, reliable electronic component, specifically a M83446/39 qualified molded unshielded chip inductor. It features a compact design with dimensions of 4.22 × 3 × 3 mm and a weight of 0.301 g. This inductor is part of the MLRF1812 series and is suitable for surface mount technology (SMT) applications, meeting QPL application grade standards. It offers an inductance of 3.3 µH, a direct current resistance (DCR) of 0.8 Ω, and a current rating of 0.501 A DC. The component operates effectively within a frequency range, with a self-resonant frequency (SRF) of 45 MHz and a test frequency of 7.9 MHz, ensuring a minimum Q factor of 50. It is designed to withstand a dielectric withstanding voltage (DWV) of 200, 80, and maintains a tolerance of ±5%. The product level is M, with a lead-based termination type and a Sn63Pb37 termination finish. The core material is ferrite, and it is not shielded. It operates within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is also fungal inert, making it suitable for various demanding applications.
